initial database code (#6)
* commit to start the draft pull request. added a space * Please don't look to close.It might hurt your eyes * impl associated types * errors, docs & divided ro/rw tx Added some more errors to DB_FAILURES, rewrited crates docs, and specified WriteTransaction subtype which implement write mode method. * more changes see description changed blockchain_db folder by database. Implemented (just for test) get_block_hash, open, from to Interface. Also rewrited a declarative macro for tables. Will have to add Dummy Tables later. * small changes * Organized modules & implemented get_block_hash * write prototype & error Added prototype functions for clear(), put() & delete() in mdbx implementation. They still don't consider table flags. Also added a temporary DB_FAILURES::EncodingError for monero-rs consensus_encode errors. Still have to rethink about it to resend a reference to the data that can't be encoded. * Multiple changes - hse.rs Added hse.rs that will contain db implementations for HSE. Since the codebase can't welcome unsafe code, the wrapper will be written outside of the project. - lib.rs Added a specific FailedToCommit error. (will investigate if really necessary). Added DupTable trait, which is a Table with DUPSORT/DUPFIXED support and its declarative macro. Added two other tables, blockheaders that give block's header with specified hash & blockbody that give block's body with specified hash Added Cursor methods, that are likely to be deprecated if I found a way to implemen Iterator on top of it. Added WriteCursor trait & methods, which is basically put & del. Added mandatory type for Cursors in Transaction & WriteTransactions Refactored get_block_hash interface method. - mdbx.rs Added partial implementation of Cursor & WriteCursor trait for libmdbx::Cursor. Only the first() & get() methods are implemented Added implementation of get & commit for Transaction * put mdbx as features with its dependency * save * refactored some method with macros * more mdbx errors, docs correction, moved to error.rs * finish nodup mdbx impl, errors.rs, macros, tables Finished the initial implementation of Cursor, WriteCursor, Transaction and WriteTransaction in mdbx.rs. Corrected some macros in mdbx.rs to simplify the implementations. There is certainly rooms to more flexible macros. Also added 3 other tables. I started to divide errors into category to more easily handle them at higher-level. Due to the large number of errors i just moved them into another file. There is know DB_SERIAL enum for errors relating of decoding/encoding error & DB_FULL enum for every errors relating a component being overeaching its capacity. * bye bye match statement in mdbx.rs * defined all blockchain tables (not txpool) * dupsort/fixed support, dupcursor, basic block interface * tables, types, encoding and documentations Redefined all the database types from @Boog900's monero-rs db branch and added the needed implementations. The database now use bincode2 for encoding and decoding. We observe that bincode was 5 times faster at serializing than monero::consensus_encode. Since we still use monero-rs types but can't implement foreign trait to them, the encoding module contain a compatibility layer, the time we switch from monero-rs to properly implement it. All the tables are now defined. (can be subject to change if there is good reason for). added documentations to modules and types. * replaced macros and added hfversion table * save * multiple changes * modified database schema. deprecated output global index and splited up pre-rct from rct output. * Fixed DupCursor function to return subkey (thx to rust turbofish inference). * Added some output functions * Added two new DB_FAILURES, one to handle a prohibited None case and one for undefined case where a dev msg is needed. * fixed TxOutputIdx, previously used global index, now is a tuple of amount/amount_index. * i hate lifetimes * read-only method now use read-only tx * initial output fn * some tx functions. Yes I'll refactor them * moved interface in a module * redefined errors, more tx fn, None->error * corrected a table + started blk fns * save * fixed TxOutputIdx + pop_block * IIRC I finished initial interface fns * fixed table name const + db build/check/open fn * switched important tables to dummy keys + rm blockhfversion * minor docs correction * fixed mentioned issues * make a test bin, just for fun * fixed issues + cargo fmt * removed monerod part * fixed a comment |
